Former state Senate Democratic Leader Robert J. Mellow has turned himself in this morning at a federal prison in South Carolina.

Mellow, a 40-year career politician who was sentenced to serve 16 months in prison for using his Senate staff for re-election campaigns, surrendered himself at a federal prison in Williamsburg, S.C., a federal Bureau of Prisons spokesman said.

He will be assigned to the prison's minimum security camp. He was ordered by the court to report today.
